A Connecticut caretaker was charged yesterday in the drug-overdose death of a prominent plastic surgeon who lost his license after he was caught using painkillers before performing surgery.

Dr. Ian Rubins, 46, was a renowned Greenwich surgeon before he was caught injecting powerful painkillers just moments before picking up a scalpel.

Officials said police found the doctor dead inside the home of a man who supplied him drugs. Cops arrested Leonard Bajramaj, 32, of Stamford, and charged him with first-degree manslaughter.

Stamford Police Capt. Richard Conklin said Bajramaj supplied or facilitated the use of an injectable drug, and failed to quickly call 911 when the victim “found himself in a medically distressed condition.”

Conklin declined to say how much time passed between Rubins’ initial distress and the emergency call that Bajramaj eventually placed Wednesday shortly before 6:30 a.m. An official said Rubins collapsed on the couch of the apartment.

“We’re waiting for a toxicology report,” Conklin said.

Conklin said Rubins and his wife hired Bajramaj to maintain their pool and fix things around their Greenwich house.

Conklin said Bajramaj, who is being held on $750,000 bond, has several prior convictions for drug-related offenses in New York and Connecticut.
